The Philadelphia Orchestra has confirmed three appointments: Jennifer Montone as principal horn, Choong-Jin Chang as principal viola and Paul Demers as bass clarinet. Montone takes her chair in September; Chang's and Demers's appointments have already begun.

Seoul native Choong-Jin Chang joined the Philadelphia Orchestra as associate principal viola in 1994. He moved to the U.S. at 13 to attend the Juilliard School and has degrees in both violin and viola from the Curtis Institute, where he studied with Jascha Brodsky and retired Philadelphia Orchestra principal viola Joseph de Pasquale.

Paul Demers has perfomed as bass clarinetist with the National Symphony and the Baltimore Symphony, among others. He has been a regular substitute with the Philadelphia Orchestra, with whom he has recorded and toured. Demers has bachelor's and master's degrees and a performance certificate from DePaul University in Chicago.

Jennifer Montone, principal horn at the St. Louis Symphony, attracted attention recently due to uncertainly over whether she would take the high profile Philadelphia position. Montone reportedly enjoys working with St. Louis conductor David Robertson, with whom she will continue to perform next season.
